摘要

本文考虑了堆积体滑坡的破坏机制和渗流过程中的降雨对滑坡现象的影响。据此，建立了不同坡度和不同降雨条件下的物理试验模型。利用三维激光扫描仪和摄像机对坡面侵蚀和滑坡动力演变过程进行了监测。利用该方法确定了土体体积含水量、孔隙水压力、土压力、边坡变形和损伤的时间变化曲线。结果表明:在相似条件下，不同坡面和降雨强度下孔隙水压力变化趋势相似;

Analysis of the Mechanisms Underpinning Rainstorm-Induced Landslides

The present study considers the damage mechanisms and the rainfall in ﬁ ltration process responsible for landslide phenomena which originate from accumulation slopes. Accordingly, a physical test model is developed for different slopes and different rainfall conditions. Moreover, a three-dimensional laser scanner and a camera are used to monitor the slope erosion and the landslide dynamic evolution. Using this approach, the time variation curves of volumetric water content, pore water pressure, soil pressure, slope deformation, and damage are determined. The results show that under similar conditions, similar trends of the pore water pressure are achieved for different slopes and rainfall intensities.
